As the ball of mud that is web standards grows, the less likely that it becomes that things can “sort themselves out”. Even as things are you need a literal army of developers to build and maintain a modern standards compliant browser, making any real threat to Chromium dominance unlikely, and that only intensifies as Google rolls ever more crap into the katamari. If users can then be harassed into switching to Chromium based browsers it’s likely that it will never be toppled short of some new technology superseding the web entirely.
